n, or carcasa, ILLINOIS SOAP-DISPENSEWG- SHAVING BRUSH Application le June 12,

rThis invention relates to soap-dispensing i shaving brushes and the like.

An object of the invention is to provide a shaving brushfof the soap-dispensing type wherein a previously prepared soap cartridge may' be'inserted, the soap to be fed to the bristles of the brush as it is needed.

:A further object of the invention is to pro# vide a brush of this type of a simple yet strong construction, in which the soap cartridge or carton may be readily inserted, and from which a carton, when empty, may be easily and quickly removed.

In accordance with the present invention l the handle of the brush comprises a barrel erably engaged between said annular member and the sleeve of the cartridge and the barrel is preferably provided, at its lower end, with a part or member adapted to form a continuation of the sleeve of said cartridge to form a uniform bore for said piston.

rlhe invention will be fully understood from the following description of a preferred embodiment thereof, taken in conjunction with the accompanying drawings, in Which- Figure 1 is a side elevation of a shaving brush embodying my invention;

Fig. 2 is a longitudinal section through the same on a larger scale; and o Fig. 3 is a section on the line 3-3 of Fig. 2.

Referring to the drawings the'embodiment of the invention illustrated comprises a longitudinal barrel or sleeve 10 which is provided exteriorly with a threaded portion 11 1929. Serial No. 370,198.

near its upper end and with a projecting ridge 12 intermediate of its length.

The threaded portion 11 is engaged by a corresponding vthreaded portion on an annular member 13 which is provided interiorly with a projectingY rib 14 which engages the fiat portion of a flexible gasket member-15 preferably of rubber, which is provided centrally with a nipple portion 15al which extends upwardly into the bristles 17, and terminates in a closed end in which one or more slots 16 are cut for the purpose of permitting vsoap cream, or paste to pass therethrough.

The bristles 17, are rigidly mounted in the annular member 13 and a central opening is provided therethrough to receive the nipple 15a. If desired the bristles, 17, the annular member 13 and the rubber member 15,15'L may be formed as anintegral unit. It is preferred to make the member 15, 15a as an independent unit, the gasket portion 15 thereof being received in a groove 13*l in the annular member 13, so that it will1not readily fall out of same, when the said annular member is removed fromthe brush. The lower end lof the barrel 10 is closed by a cup member 18, the skirt of which extends upwardly approximately to the upper side of the ridge 12 of the barrel 10. The cup member 18 is threaded interiorly at its upper edge as shown at 19, which threaded portion is engaged by a corresponding threaded portion of a ring 20 provided with a shoulder 21 which engages the upper side of the ridge 12, and With a knurled exterior surface 22. Between the annular member 13 and the ring 20, the ex-v posed surface of the 'barrel 1() is knurled as shown at 10a in Fig. 1.

On the lower end or bottom of the cup member 18 is rigidly mounted a threaded stem 23 so that it rotates with said cup. The shell or carton of the soap cartridge is designated by the numeral 24. This shell, like the barrel 10 is preferably of circular cross section, fits snugly into said barrel and, when fully inserted, preferably extends upwardly slightly above the upper edge of the barrel 10. At the lower end of the interior of the barrel a ring 25 is provided, which is either integral therewith or rigidly inserted therein with a drive fit or other means of attachment. Said ring forms an abutment for the cartridge shell 24 and constitutes a continuation of same for more effective cooperation with the piston which is designated generally by the numeral 26.

The piston 26 comprises a plate member 27 provided with an upstanding boss 28 which is threaded interiorly to co-operate with the stem 23 with a nut plate 29. Between the plates 26 and 29 are engaged a metal washer 30 and a fiexible washer, 31 preferably of leather, which is turned upwardly so as to form a circumferential seal.

As indicated, the member 15, 15a is preferably formed of rubber, ,and the washer 31 of leather. The remainder of the brush, with the exception of the bristles, may suitably be made of metal,preferably of ali ght metal,such as aluminum. The soap cartridge shell 24 is preferably also of aluminum although it may be made of other metal or other materials, such as paper, cardboard, or the like.

The operation of the brush will now be described. Assuming that the soap-chamber has been exhausted, the cup member 18 is rotated in a counterclockwise direction with respect to the barrel 10 so as to retract the piston 26 to the position illustrated in Fig. 2. The annular member 13 is now unscrewed from the barrel 1G and removed together with the rubber member 15 and the bristles 17. The empty shell 24 is now removed and a full cartridge of soap cream or paste, including a shell 24, is placed in the barrel 10. If desired the shell 24 may be retained in position and be refilled with soap cream from any desired source.

The annular member 13 is now applied to the barrel 10 and is screwed tightly thereon until the' gasket 15 is firmly compressed between the rib 14, and the upper edge of the sleeve 24. The brush is now ready for use. It will be readily understood that by clockwise rotation of the cup 18 with respect to the body 10 or annular member 13, the threaded stem is rotated'within the piston 26, and the latter is caused thereby to move longitudinally of the chamber 10, causing a regulable amount of soap to be expressed into the bristles of the brush through the slot 16. The friction between the piston and the soap and the' shell 24 prevents rotation of said piston with the stem 23, and no structural means are necessary to prevent such rotation.

While I have described and shown only a sin gle embodiment of the invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made which do not depart from the spirit and scope of the invention, as disclosed in the appended claims.
